To all whom it may conccm:

Be known that l, Tnonixs M. limin- GAN, of ll oods'toclr, in the countyof Wind sor, and in lhe Slato of Vermont, have invented u'certuin nowand useful improvement in Couplers for the Spawning-Chains of LightingApparatus and do hereby declare um: the following is a full, clear,

x and eimct description lhcreoi.

My invention'rclutcs to tho pcndcnl, chains cinploycd to operate valvesof gus burncrs and the sparking lQVlCG of clcctric gas hghl'ersfand ijheswilchcs of GlQCilllC lumps,

and my object is to provide splice or couis a perspective View ol? :1pendent chain Wllll parts or sections thereof joinod by one of mycouplern; l 2 a similar View showing u portion of a pendent chain and ucord or string connected by one of my couplers; and Fig. 3 is :L detailVlGW in perspective and on. an enlarged scale of one of my couplersbefore i'rs application in use.

The pendent chain for which my invenbion has been specifically adaptedconsists of a series of bend-like balls 10 flexibly joined together, andmy coupler 11 is so constructed that it forms a scat or socket for thelink of adjoining portions or sections of a chain,

said coupler consisting of a strip of flexible or easily bent shcclxmetal in the form of a letter S, ouch end portion of which has a slit orslot 12 llmt cxteuds from 'lJhe ext-romifly of the end. portion inward,the slit or slot being rounded or cnlurgcd at its inner end at 18. Itwill thus oe seen that each end of the coupler being forked lnsy beslipped between tho adjoining bonds or links of the chain so thatthc'comiccting member between two links will occupy lhe enlarged roundedinner end ol the slit or slotand the outermost hood or link scaled inihc curvc or bend of the coupler and the free projecting end of thecoupler may be bent toward the intermediate portion of the coupler so asthereby closely to confine and hold the head or link, the coupler inthis condition being as illustrated in Figs. 1 and 2. As illustrated inFig. 3, before the coupler is applied, the free ends are sullicientlyspaced from the intermediate, unslotted portion of the" coupler toenable the ready passage of the chain bend or link into its seat.

As shown in Fig. 2, besides connecting two sections of chain together,-a section of chain and s cord or string M may be connected together, aknot being provided on the cod of the cord to occupy the seat or socket,formcd by the bend of the coupler. It will hc secn filial, should aportion of in sululxion between the part of the pendant um is lo becaughlfby l3he hand and the metallic ch: desired, my coupler recdilysdinilsof his bcing done, because the stringo! cord illustrated in Fig.2 may be of insulating material.

Having thus described my invention, Wh'st I claim 15:

1. In or device of the class described, a strip of flexible material haiing reverse bends at opposite ends, each of said ends being slotled'fromits extremity inward, the

slotted end portions lying contiguous to the" inlermediute connectingportion and forming therewith e retaining seat or socket.

2. The combination of two parts to be joined, each having anenlargement, and a ship of flexible material haying revcrsed bends atopposite ends, each of said" ends being slotted from its extremityinward, the slotted nortions being contiguous to the intermediutc bodyportion and each forming therewith a holding seat or socket in which theenlargement of one of the parts to he joined is sealed, the portion ofsaid part to be joined contiguous to [its enlargement passing throughthe slot.

In testimony that I claim the have hercunto set my hand. 7
